Gain or lose
Iron is a metal element. There are 26 electrons in a single atom.
No. Atoms can gain and lose electrons but seldom gain or lose protons.
gain
Those electrons are the valence electrons. They are the electrons which mostly take part in exchange of electrons or sharing of electrons. Hence, valence shell electrons are a very important part of chemistry since all the reactions due to them only.
Fluorine tends to gain electrons
They will loose electrons.
Metals lose electrons, nonmetals gain electrons.
Iron loose electrons and form cations.
It gains three, loses five, or shares pairs of electrons
Atoms can lose or gain electrons. When they do, they form charged particles called ions: if an atom loses one or more electrons, it becomes a positively charged ion, I think ;]
ions
They need to gain them.
Metals loss electrons and nonmetals gain electrons.
0 he has glasses
Metals will LOSE electrons to become stable.
P has 5 valence electrons so it can gain 3 electrons or lose 5 electrons to have a full valence shell.
